How to Water - over head or at the base of the plant

Which way should you water your plants? When it comes to vegetables there are certain plants it is best to take precautions with and NOT do overhead watering. Tomatoes, peppers, squash, cucumbers and watermelons in particular are all plants that get fungal diseases (blights and powdery mildew.)


These tomatillos have lots of space at the
bottom so they can be watered easily at
the base without getting the leaves wet.
Wet leaves set up the perfect conditions for disease to get established. For these plants it is much better to water at the base (ground level) and not get the leaves and stems wet.

You can't control the amount of water that comes from the sky but you can control where you place the water when you are hand watering.

There are 4 or 5 tomatoes in here. Only one
is easy to water without getting the foliage wet.
The only choice IS to water through the leaves.
But....there is always a BUT....if we haven't had any rain for several weeks it is a good idea to give the plants a shower to wash the dirt and grime off the leaves.



Carrots






Any time you wash a plants leaves off, do it early enough in the day (at least an hour before dark) to give the foliage time to dry before dark.

Carrots, lettuce, and greens on the other hand, like to get their foliage washed when they get watered. So you can do overhead watering frequently on them. As you can see above, it is hard to water just at the base of a carrot in a bed of carrots so you do have to get the foliage wet every time you water.
